For the purpose of obtaining latere-l bilit the main lever 9 of the seele is pun ed at its center iure a sulietentialiy nular portion i0, and the ends of the if.- 9 are likewise expanded to form ennuis-ir portions 11 and l2 (see Figure 3), Uu

The chart 33 is graduated in, the well-known manner so that Weight of the ioad on the comlity-zeeeiver may be read directly in and, ounces, and, it' desired, value be marked thereon at va- Dcund. Should the load 'p n he so great rely across the Acose countern the pan 'ocnduiuin Upon the ree end of this lion. f E. andpontainsl a plunger to 1- in oil, the plunger' vloose counterweights on the pan 15 to the weight indicated on the chart 33. Movement of the dash pot plunger is retarded by the oil or other Huid in the' dash pot, and since the plunger is connected to the lever 9 by incansof the link 38, the oil will serve to dampen vibration of the weighing mechanism of the scale.

It will be observed by inspection of Figure` 1 that the commodity-receivin pan 1s located directly in front of the c art 33. In most of the weighing operations in which the scale is likely to beI used the loose weights will not be employed. The operation in such case will consist merely in placing the commodity upon the pan and reading the weight on the chart.

In case it is desired to use the device as a ypredetermined weight scale, the parts formingv the weighing mechanism are so proportioned and arranged thatv the indicator 32 stands in a. vertical position when the commodity-receiving pan vand counterweight-receiving pan are empty. A poise of the desired weight is then placed upon 4the counterWeight-receiving pan 15 and the article the Weight of which is to be tested is placed upon the commodity-receivi pan 24. -Should the article be over-wei t the indicator hand will move to the'rigit, and should it be underweight the indicator hand will move to the le'it, the amount of over or under-weight being shown on the chart.

While it will be apparent that the illustrated embodiment of my invention herein disclosed isi well' calculated to adequately fulfill thc objects primarily stated, it is to bennderstood that the invention is'susceptible to variation, modification and change within the spirit and scope of the subjoined `single laterally extending lever fulczminefi thereon, a commodity-receiver and a' oisereceiver on said lever on o poeite si es of its fulcrum, automatic loa -counterbalancing mechanism connected to said lever, .a chart at the rear of and facing said commodity-receiver, and an indicator connected to said load-counterbalancing mechanism andA movable over said chart.
